Description

Technical Field

[0001] This application relates to the field of fire protection equipment technology, specifically a fire hose fastening device. Background Technology

[0002] As the core equipment for fire rescue, fire trucks must ensure that their fire extinguishing tools, such as water guns, can be quickly accessed and reliably secured. This is especially true for small motorized fire extinguishing equipment such as fire motorcycles, where space constraints place even greater demands on the convenience and stability of the water gun securing devices.

[0003] In the prior art, utility model patent CN210114762U provides a quick-fastening device for water guns on fire-fighting motorcycles. It consists of a frame structure formed by a base plate, an upper mounting plate, and side connecting plates. The water gun is clamped by the upper arc-shaped groove of the pressure plate and the lower arc-shaped groove of the base plate, and pre-tensioning force is provided by an elastic band. Rectangular inserts and slots are used to achieve quick assembly and disassembly of the pressure plate. This quick-fastening device for water guns on fire-fighting motorcycles allows for convenient fastening of the water gun, saving time on fixing operations and making it very convenient to remove the water gun at a fire scene, avoiding delays in disaster response. It is highly practical and conducive to widespread adoption.

[0004] However, in actual operation, the aforementioned existing device uses multiple pressure plates to secure the water gun. During operation, the position of each pressure plate must be adjusted and the insert block must be inserted one by one, which makes the operation steps cumbersome and time-consuming. This may delay the disaster situation, especially in emergency rescue scenarios. In addition, multiple independent rectangular insert blocks and other components are prone to being lost or damaged during high-frequency use, affecting the reliability and service life of the device.

[0005] Therefore, this application provides a fire hose fastening device to solve the above-mentioned problems. Utility Model Content

[0006] This application provides a fire hose fastening device, which aims to solve the problems of cumbersome operation, easy loss of parts, and unstable fixation in the prior art as mentioned in the background art.

[0007] To achieve the above objectives, this application provides the following technical solution: a fire hose fastening device, comprising a mounting plate installed on a fire truck, a positioning plate fixedly disposed at the bottom of the mounting plate, a fixing hole plate movably disposed at the top of the mounting plate, and an elastic driving member for driving the fixing hole plate to move closer to the positioning plate; the elastic driving member includes a guide frame plate fixedly connected to the top of the mounting plate, a slider slidably disposed within the guide frame plate and fixedly connected to the fixing hole plate, and a spring disposed within the guide frame plate and fixedly connected to the upper end of the slider; a guide rod fixedly connected to the guide frame plate is slidably inserted into the slider, and the spring is sleeved on the guide rod. This fastening device, through the upper and lower cooperation of the positioning plate and the fixing hole plate, combined with the automatic pressing function of the elastic driving member, achieves rapid fastening and convenient retrieval of the fire hose, significantly improving the efficiency of fire hose retrieval and deployment in firefighting operations. The structure adopts a modular design, and the mounting plate can be adapted to different positions on the fire truck. The coaxial layout of the positioning plate and the fixing hole plate ensures that the water gun is evenly stressed and avoids eccentric shaking. The elastic drive component uses the continuous elastic force of the spring to provide stable clamping force, eliminating the need for frequent manual adjustments. It can not only meet the fixation stability under the vibration environment of the fire truck, but also complete the loading and unloading of the water gun through simple up and down movement in emergency situations, effectively shortening the rescue preparation time.

[0008] Preferably, to facilitate the fixing of the mounting plate to the fire truck: multiple mounting holes are symmetrically provided on both sides of the mounting plate for fixing the mounting plate to the required position on the fire truck. By providing multiple mounting holes on both sides of the mounting plate, the installation position can be flexibly adjusted according to the actual installation requirements of the fire truck, ensuring that the fastening device is compatible with the fire truck structure; at the same time, the symmetrically distributed mounting holes can distribute the force evenly, improving the stability of the entire fastening device after installation, avoiding loosening due to vibration or external force, and ensuring the reliability of the water gun fixing.

[0009] Preferably, to facilitate and ensure stability when the large end of the water gun is fixed: a tapered tube is fixedly connected to the upper end of the positioning plate, and the large end of the tapered tube is arranged facing the fixing orifice plate. The axis of the tapered tube and the axis of the fixing orifice plate are located on the same vertical line. The tapered surface structure of the tapered tube can form multi-angle limiting for the large end of the water gun. Regardless of the water gun diameter (within the range of the tapered tube's compatibility), automatic centering can be achieved through the tapered surface fit, significantly improving the stability of the water gun when placed on the positioning plate. At the same time, the collinear design of the axes ensures that the clamping force of the fixing orifice plate and the positioning plate on the water gun is evenly distributed, avoiding shaking caused by eccentricity.

[0010] Preferably, to reduce wear on the water gun from the conical tube: a first silicone pad is fixedly provided on the inner side of the conical tube to abut against the water gun. The silicone material has elastic cushioning properties, which can effectively reduce rigid contact between the water gun and the conical tube, avoiding wear and scratches on the water gun surface caused by long-term friction or vibration, and extending the service life of the water gun; at the same time, the anti-slip performance of the silicone pad can enhance the friction between the water gun and the conical tube, further improving stability when fixed.

[0011] Preferably, to reduce wear on the water gun caused by the fixing orifice plate, a second silicone pad is fixedly provided on the inner side of the fixing orifice plate to contact the water gun. The second silicone pad can buffer the pressure of the fixing orifice plate on the small end of the water gun, avoiding surface damage caused by the fixing orifice plate directly squeezing the water gun; at the same time, the flexible contact of the silicone pad can adapt to the irregular shape of the water gun surface, enhance the fit between the fixing orifice plate and the water gun, ensure uniform pressure distribution during fixing, and improve the overall fixing stability.

[0012] Preferably, to facilitate the movement of the fixed orifice plate: a protruding rod is fixedly provided on the outer side of the fixed orifice plate, and a ball is fixedly connected to the end of the protruding rod away from the fixed orifice plate. The protruding rod and the ball constitute an operating handle. The rounded shape of the ball makes it easy for firefighters to grip when wearing gloves, avoiding the slippage or hand-gripping problems that may occur with traditional straight rod structures. The outward protrusion design of the protruding rod extends the operating lever arm of the fixed orifice plate, reducing the pulling force required during operation and improving the convenience and efficiency of picking up and releasing water guns.

[0013] Preferably, to further ensure the stability of the water gun's fixation: the guide frame plate is provided with a locking element for locking the position of the slider. The locking element includes a vertical groove formed in the guide frame plate, and a knurled screw that is threaded into the slider is disposed in the vertical groove. The knurled screw can lock the slider at any position on the guide frame plate, thereby locking the position of the fixing plate and preventing loosening of the fixing plate due to long-term spring fatigue or accidental vibration. This is particularly suitable for scenarios requiring long-term fixation of the water gun or demanding extremely high stability, further improving the reliability of the device.

[0014] This fastening device, through the upper and lower cooperation of the positioning plate and the fixing hole plate, combined with the automatic clamping function of the elastic drive component, achieves rapid fixing and convenient access to the water gun, significantly improving the efficiency of water gun retrieval and placement during firefighting operations. Structurally, it adopts a modular design; the mounting plate can be adapted to different installation positions on the fire truck. The collinear layout of the positioning plate and the fixing hole plate ensures uniform force on the water gun, avoiding eccentric swaying. The elastic drive component utilizes the continuous elastic force of the spring to provide stable clamping force, eliminating the need for frequent manual adjustments. This not only meets the stability requirements under the vibration environment of fire truck travel but also allows for simple up-and-down movement of the water gun for loading and unloading in emergencies, effectively shortening rescue preparation time.

[0015] This application uses knurled screws to lock the slider at any position on the guide frame plate, thereby locking the position of the fixing plate and preventing the fixing plate from loosening due to long-term fatigue of the spring or accidental vibration. It is especially suitable for scenarios that require long-term fixing of water guns or have extremely high requirements for fixing stability, further improving the reliability of the device.

[0018] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0019] Example 1 This embodiment provides a fire hose fastening device, such as... Figure 1-3As shown, the fastening device includes a mounting plate 1 installed on the fire truck, a positioning plate 2 fixedly installed at the bottom of the mounting plate 1, a fixing hole plate 3 movably installed at the top of the mounting plate 1, and an elastic drive member 4 for driving the fixing hole plate 3 to move closer to the positioning plate 2; the elastic drive member 4 includes a guide frame plate 41 fixedly connected to the top of the mounting plate 1, a slider 42 slidably installed in the guide frame plate 41 and fixedly connected to the fixing hole plate 3, and a spring 43 installed in the guide frame plate 41 and fixedly connected to the upper end of the slider 42. A guide rod 44 fixedly connected to the guide frame plate 41 is slidably inserted into the slider 42, and the spring 43 is sleeved on the guide rod 44. The elastic drive component 4 provides a continuous downward driving force to the fixed orifice plate 3 through the elastic force of the spring 43, ensuring that the fixed orifice plate 3 and the positioning plate 2 always remain clamped to the water gun, preventing the water gun from loosening due to vibration or external force. The guide frame plate 41 and the guide rod 44 form a sliding guide structure, limiting the movement direction of the slider 42 (vertical direction only), preventing the fixed orifice plate 3 from shifting or jamming during movement, and ensuring the reliable operation of the device. The charging and releasing process of the spring 43 does not require external power and can be completed by manual operation, combining energy saving and ease of operation.

[0020] This fastening device, through the upper and lower cooperation of the positioning plate 2 and the fixing hole plate 3, combined with the automatic clamping function of the elastic drive component 4, achieves rapid fixing and convenient access to the water gun, significantly improving the efficiency of water gun loading and unloading during firefighting operations. Structurally, it adopts a modular design; the mounting plate 1 can be adapted to different installation positions on the fire truck. The collinear layout of the positioning plate 2 and the fixing hole plate 3 ensures uniform force on the water gun, avoiding eccentric swaying. The elastic drive component 4 utilizes the continuous elastic force of the spring 43 to provide stable clamping force, eliminating the need for frequent manual adjustments. This not only meets the stability requirements of fire truck movement under vibration but also allows for simple up-and-down movement to load and unload the water gun in emergencies, effectively shortening rescue preparation time.

[0021] Installation process: Pull the fixing plate 3 upwards, causing the slider 42 to slide within the guide frame plate 41 and compress the spring 43, allowing the spring 43 to store elastic potential energy; place the large nozzle end of the water gun on the positioning plate 2, ensuring that the axis of the water gun is aligned with the axes of the positioning plate 2 and the fixing plate 3, then release the fixing plate 3. The elastic force of the spring 43 pushes the slider 42 downwards, causing the fixing plate 3 to fit over and press the small nozzle end of the water gun. Through the support of the positioning plate 2 and the downward pressure of the fixing plate 3, the water gun is clamped and fixed from top to bottom.

[0022] Disassembly process: Pull the fixing plate 3 upward to overcome the elastic force of the spring 43 and move it upward. When the hole of the fixing plate 3 is separated from the small end of the water gun, the water gun can be directly removed from the positioning plate 2. The operation process only requires linear movement in one direction and does not require complicated unlocking or disassembly steps.

[0023] To facilitate the fixing of mounting plate 1 to the fire truck, multiple mounting holes are symmetrically provided on both sides of mounting plate 1 for fixing it to the required position on the fire truck. By providing multiple mounting holes on both sides of mounting plate 1, the installation position can be flexibly adjusted according to the actual installation needs of the fire truck, ensuring that the fastening device is compatible with the fire truck structure. Simultaneously, the symmetrically distributed mounting holes ensure even force distribution, improving the stability of the entire fastening device after installation, preventing loosening due to vibration or external forces, and ensuring the reliability of the water gun fixation. During installation, mounting plate 1 is aligned with the target installation position on the fire truck, and bolts, screws, or other fasteners are passed through the mounting holes and connected to the fire truck structure to secure the fastening device. Disassembly is performed by reversing the process. The symmetrical design and numerous layout of the mounting holes provide convenient positioning and structural stability during installation.

[0024] To ensure stability when the water gun's large nozzle is fixed, a tapered tube 21 is fixedly connected to the upper end of the positioning plate 2, with the large nozzle of the tapered tube 21 facing the fixing orifice plate 3. The axis of the tapered tube 21 and the axis of the fixing orifice plate 3 are on the same vertical line. The tapered surface structure of the tapered tube 21 can provide multi-angle limiting for the large nozzle of the water gun. Regardless of the water gun's nozzle diameter (within the compatibility range of the tapered tube 21), automatic centering can be achieved through the tapered surface fit, significantly improving the stability of the water gun when placed on the positioning plate 2. At the same time, the collinear design of the axes ensures that the clamping force of the fixing orifice plate 3 and the positioning plate 2 on the water gun is evenly distributed, avoiding shaking caused by eccentricity. When the large end of the water gun is placed on the tapered tube 21, the outer wall of the water gun contacts the tapered surface of the tapered tube 21. The guiding effect of the tapered surface makes the water gun naturally align with the axis. At the same time, the radial contraction structure of the tapered surface (the large end faces the fixed orifice plate 3) forms a downward limiting force on the water gun. Combined with the pressure of the upper fixed orifice plate 3, it achieves bidirectional fixation. Water guns of different diameters can fit tightly against the tapered tube 21 due to the adaptability of the tapered surface, which expands the applicability of the device.

[0025] To reduce wear on the water gun caused by the conical tube 21, a first silicone pad 211 is fixedly installed on the inner side of the conical tube 21 to contact the water gun. The silicone material has elastic cushioning properties, effectively reducing rigid contact between the water gun and the conical tube 21, preventing wear and scratches on the water gun surface caused by long-term friction or vibration, and extending the service life of the water gun. Simultaneously, the anti-slip properties of the silicone pad enhance the friction between the water gun and the conical tube 21, further improving stability during fixing. When the water gun is placed on the conical tube 21, the outer wall of the water gun fits tightly against the first silicone pad 211, and the elastic deformation of the silicone pad fills the tiny gaps, eliminating rigid contact points. During fire truck movement or firefighting operations, the silicone pad absorbs vibration energy, reducing the relative displacement between the water gun and the conical tube 21, thereby reducing wear and improving fixing reliability.

[0026] To reduce wear on the water gun caused by the fixing orifice plate 3, a second silicone pad 31 is fixedly installed on the inner side of the fixing orifice plate 3 to contact the water gun. The second silicone pad 31 can buffer the pressure of the fixing orifice plate 3 on the small end of the water gun, avoiding surface damage caused by the fixing orifice plate 3 directly squeezing the water gun; at the same time, the flexible contact of the silicone pad can adapt to the irregular shape of the water gun surface, enhance the fit between the fixing orifice plate 3 and the water gun, ensure uniform pressure distribution during fixation, and improve the overall fixation stability. When the fixing orifice plate 3 moves downward under the action of the elastic drive 4 and covers the small end of the water gun, the second silicone pad 31 contacts the outer wall of the water gun. The elastic deformation of the silicone pad allows the fixing orifice plate 3 to adapt to the outer diameter of the water gun and fix the upper end of the water gun through friction and pressure; during disassembly, the flexible characteristics of the silicone pad also facilitate the separation of the fixing orifice plate 3 from the water gun, reducing operating resistance.

[0027] To facilitate the movement of the fixed orifice plate 3, a protruding rod 32 is fixedly installed on the outer side of the fixed orifice plate 3, and a ball 321 is fixedly connected to the end of the protruding rod 32 away from the fixed orifice plate 3. The protruding rod 32 and the ball 321 constitute an operating handle. The rounded shape of the ball 321 makes it easy for firefighters to grip when wearing gloves, avoiding the slippage or hand discomfort that may occur with traditional straight rod structures. The outward protrusion of the protruding rod 32 extends the operating lever arm of the fixed orifice plate 3, reducing the pulling force required during operation and improving the convenience and efficiency of retrieving and releasing the water gun. When it is necessary to retrieve or release the water gun, the firefighter holds the ball 321 and pulls the protruding rod 32 upward, causing the fixed orifice plate 3 to move upward against the elastic force of the spring 43. The surface curvature of the ball 321 and the length of the protruding rod 32 are designed to optimize the direction of force application, making the operating force more ergonomic. Even in emergency situations, the movement of the fixed orifice plate 3 can be completed quickly and effortlessly, shortening the time required to retrieve and release the water gun.

[0028] Example 2 Unlike Embodiment 1, to further ensure the stability of the water gun fixation, a locking element 5 for locking the position of the slider 42 is provided on the guide frame plate 41. The locking element 5 includes a vertical groove 51 formed on the guide frame plate 41, and a knurled screw 52 that is threaded into the slider 42 is provided in the vertical groove 51. The slider 42 can be locked at any position on the guide frame plate 41 by means of the knurled screw 52, ​​thereby achieving position locking of the fixing plate 3 and preventing the fixing plate 3 from loosening due to long-term fatigue of the spring 43 or accidental vibration. This is especially suitable for scenarios that require long-term fixation of the water gun or have extremely high requirements for fixation stability, further improving the reliability of the device. After the fixing plate 3 presses the water gun, rotate the knurled screw 52 so that its threaded end is inserted into the corresponding threaded hole of the slider 42, and fix the slider 42 to the guide frame plate 41. The knurled design on the outer surface of the knurled screw 52 makes it easy to tighten and loosen manually without tools. After locking, the elastic force of the spring 43 and the mechanical locking force of the knurled screw 52 work together to form a double fixing effect, ensuring that the water gun remains stable under extreme working conditions.

[0029] It should be noted that many of the standard parts used in this application are available on the market, while non-standard parts can be specially customized. The connection method used in this application is also a very common method in the mechanical field, and will not be described in detail here.

[0030] The above description is merely a preferred embodiment of this application, but the scope of protection of this application is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this application, based on the technical solution and concept of this application, should be included within the scope of protection of this application.
